I started off with 16 mg. My boyfriend (R) had taken 16mg with a very intense trip, and considering I usually have harder trips than others I decided to split the dose with him, each of us taking 8 mgs. We took it at night, which may have been the first mistake, as I soon learned what a wonderful thing the sun is.

Summary
2,5-Dimethoxy-4-propylphenethylamine (also known as 2C-P) is a lesser-known novel psychedelic substance of the phenethylamine class. 2C-P is a relatively obscure member of the 2C-x family of psychedelic phenethylamines, which are closely related to the classical psychedelic mescaline. It is known as one of the most potent, dose-sensitive, and long-lasting of the series.
Perspectives
“I was not feeling so good. Hangover, I guess. The material was so gentle in coming on, and soon my body became jangled. Thinking was easy. Verbalizing was easy. Being comfortable with my body was not. My back hurt and then my legs hurt. My lower back was in spasm. At first I did not particularly like what this drug was doing to my body, but took a good look at it and decided that I was the culprit. Took a good look at my drinking so much, and decided that I didnโt need it. So much energy was going through me I didnโt know what to do with it. The whole day was spent in physical discomfort. Food tasted good, and we nibbled all day. My stomach was bloated. Next day I was more or less like a zombie. I was wiped out.”

Typical psychedelic acute tolerance appears within the same day and decays over ~1โ2 weeks; crossโtolerance with other serotonergic psychedelics is expected. Data are based on community guidelines for psychedelics generally; specific 2CโP pharmacokinetics are not established.

Aggregated from 85 Erowid and 39 Bluelight experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect, something witnessed, or "did not happen" count too). Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

Erowid 8 reports 1 positive 4 neutral 3 cautionary visit
First of all. This was an AMAZING trip. I took the 10 mg at about 14:00. My mates and got on a bus and we went down to Little Venice. We wondered around for a couple of minutes and after about 30 minutes I started feeling it kicking in.
So I'm sitting here, wondering how exactly to put the events of the last 3 days of my life into words. It seems to me so much of the psychedelic experience gets lost when trying to describe that which totally defies words, that I have never felt motivated to sit down and write a trip report beyond basic effects descrip...
[Erowid Note: Two samples of powder (even of the same chemical) with equivalent volumes won't necessarily weigh the same. For this reason, eyeballing is an inaccurate and potentially dangerous method of measuring, particularly for substances that are active in very small amounts.
I had received some pills of 10mg 2C-P from a friend as a gift. I told my friend James and we set Tuesday July 13 as the day we would do it, planning to meet at my apartment around 12p. I wake up around 11a, make and eat some scrambled eggs.
A Mad Fucking Trip. So here it is in all its mad fucking glory. Canยt say itยs all in chronological order but itยs as good as I can remember it. This is the edited version, as I feel I learnt some truths that only I should know.
I lay in a tent on a pile of bricks with mangled, dead pigs lying all around. I chuckle every now and then, or imagine that I am speaking. I'm interested in nonsensical conversation but can't express everything I need to say.
In addition to the 2c-p we smoked a fairly constant supply of opium and marijuana throughout the day. The other day I parachuted 16 mg of 2c-p. Two of my friends did the same. Not realizing the small discrepancy between a normal dose and an overdose. I can safely inform all of you that 16 mg is indeed an *overdose*.

This is a report of my so far one and only experience with this compound. It was a sunny day last July owhen I ingested the material, toward the evening of what had been a lazy, quiet day for me spent mostly inside up to that point apart from a visit to the gym earlier.
It was a busy weekโpapers and studying filled every waking moment. Despite my unfavorable situation, I managed to plough through the sea of work. A relaxing Saturday was in order; I was in the mood for some self-reflection and much deserved free time.

Ok, while my brain felt cracked out, i wrote the following while still slightly tripping, hungry, and very tired: -------- Going to make this short, because, i'm hungry, and need sleep. 3 of us took ONE MILLIGRAM of 2c-p, and now i look at 2c-e, 2c-d, my fav's of the 2c's, look like ...toys/tools.

Ingest 2 capsules each containing 8mg of 2C-P. Begin to feel a bit amped up and very stimulated. Shaking violently, starting to feel cold. Visuals are very subtle at this point but somewhat noticeable with everything looking more colorful. Shaking harder.โฆ
